United States Patent CASING FOR INDIVIDUAL BOTTLES AND OBJECTS 0F LIKESHAPE Application July 9, 1954, Serial No. 442,406

Claims priority, application Denmark July 13, 1953 1 Claim. (Cl. 229-90)This invention relates to a package including a casing of fibrousmaterial for individual bottles and objects of like shape wherein thecasing conformably encloses a substantial portion of the bottle.

The main object of the invention is to provide a package of theaforesaid nature wherein the casing grips the bottle in such a mannerthat it cannot slip out of the casing. The drawback pertaining topreviously known casings of fibrous material and of approximately thesame shape as straw receptacles, viz. that the bottle is easily droppedthrough the open bottom of the casing, is hereby obviated.

Another object of the invention is to provide a casing suitable forbottles which are transported in cases in the same way as bottled beer,i. e. lying in tiers, the bottles of succeeding tiers being arranged inopposite directions in order to save space.

A further object of the invention is to produce a casing of the abovetype on a suction mould by sucking up suspended fibrous material.

A still further object is to construct the package in such manner thatthe contents of the bottle may be poured without removing the casing.

With the above and other objects in view the present invention consistsin the combination and arrangement of parts, hereinafter more fullydescribed, illustrated in the accompanying drawings and morespecifically pointed out in the claim, it being understood that changesmay be made in the form, size, proportions, and details of constructionwithout departing from, or sacrificing any of the advantages of theinvention.

In the drawings Fig. 1 is an elevational view which shows a casingaccording to the invention as seen from the internal side in unfoldedcondition,

Fig. 2 is the same casing, as seen from its top edge,

Fig. 3 is the same casing, as seen from one lateral edge,

Fig. 4 is a package including a casing folded to enclose a bottle, whichis seen from the side, the casing being cut through vertically,

Figs. 5 and 6 are top and bottom plan views, respectively, of thepackage,

Fig. 7 shows on a larger scale a section on the line VII-VII in Fig. 1through the casing material, and

Figs. 8 and 9 are fragmentary elevational views to show otherembodiments of the internal projections on the package.

The casing illustrated in the drawings comprises three sections it}, 12,and 14, which are swingably connected with one another along lines 16and 18, along which the sections are folded relatively to one anotherwhen the casing is to be used for a bottle 20. Hereby the lines 16 and18 will be positioned along generatrices on the cylindrical portion ofthe bottle.

As appears from Figs. 13 the sections 10, 12, and 14 are shaped asoblong vessels, consisting of an intermediate portion 22, which isshaped as part of a circular cylinder, a tapering top portion 24, and abottom portion 26. In the unfolded condition shown in said figures theedges of the three sections are disposed in the same plane. This isconvenient primarily with a viewof manufacturing the package, it beingdesigned for production on a suction mould by sucking up suspendedfibrous material in a manner known per se. Regarding this manufacturingprocess the package is furthermore divided into three or possibly moresections, so that no part of the internal surface of the package willform so small an angle with the direction, wherein the material suckedup is to be removed from the suction mould, as to involve ditficultiesin removing the material. This will beseen particularly when viewingFig. 2, wherein the surface of the package facing downwards should beconsidered as facing the suction mould.

When the casing is to be used for enclosing the bottle 20, theindividual sections 10, 12, and 14 are folded around same, the materialbeing folded along the lines 16 and 18. Hereby the casing will enclosepart of the bottle conformably, thetop portions abutting against thetapered part of the bottle at the zone between thecylindrical part andthe neck, which latter, however, remains uncovered. Each bottom portion26 will extend a distance inwardly below the bottom of the bottle, atriangular field 28 of the bottom remaining uncovered, see Fig. 6.

When the package has been folded around the bottle, the outermostlateral edges thereof abutting against one another are united, e. g. bymeans of a wafer 30, as indicated in Fig. 4. The described form of thepackage involves that the bottle 21 cannot slip out of the package,either upwardly or downwardly, which aiiords a good security againstdropping the bottle.

As the neck of the bottle is free, the contents may be poured withoutremoving the casing. On the other hand, the latter extends so farupwardly that bottles disposed in alternate directions in a case willnot be in direct contact.

As will be seen in Fig. 4 to the right, the top of each section extendsto the intersecting curve between the surface of the bottle and a planethrough the outermost generatrices of the said section, and each sectionextends inwardly below the bottom of the bottle to the said plane. It isthereby obtained that the edges of the sections in unfolded conditionwill be disposed in the same plane, see Fig. 2. The top portions 24 andthe bottom portions 26 need not, however, extend as far inwardly as tothe said plane, it being possible, for instance, to shorten the formeras shown by a dot-and-dash line 32 at the right hand side of Fig. 4,whereas the latter e. g. might end at'a curved line 34 as indicated inFig. 6. A casing of this altered form can also easily be produced on asuction mould and affords sufficient security against the bottleslipping out of the casing.

The casing is suitably produced with projections 36 facing inwardlytoward the bottle, which projections e. g. may extend along the internalsurface of the casing as shown in Fig. 1 in the form of a rib pattern.Such sup porting ribs are known per se in connection with packages forbottles and other fragile objects.

According to the invention said projections are produced as shown inFig. 7, so that the thickness of the casing material at the projections36 exceeds that of the material between the projections. Hereby alenient support of the bottle is achieved. This special design of theprojections is easy to provide as the package is produced on a suctionmould. in Fig. 7 the wall of the mould is denoted 38. In this wall thereare provided grooves or depressions 4-0, which through ducts 42 are inconnection with the hollow space of the mould, whence the suction iseffected during the depositing of the fibre suspension on the surface ofthe mould. A wire netting 44 is placed 3 in the usual manner on the saidsurface and depressed into the grooves 40. During suction the fibrousmaterial will be deposited as indicated in Fig. 7. It will be seen thatthe thickness of the wall 46 between the projections 36 is considerablysmaller than at the said projections.

The projections 36 which in the form illustrated contribute effectivelyto protect the bottle against shocks and blows may also be disposedpoint by point as shown in Fig. 8 and 9 in the shape of squares 48 orcircles 50, respectively, or they may be designed in any other suitableHaving now fully described our invention we claim as new and desire tosecure by Letters Patent:

A molded pulp casing for bottles comprising an inner section and twoouter sections, one outer section being integrally hinged to one edge ofsaid inner section and the other outer section being integrally hingedto the opposite edge of said inner section, each of said sections beinggenerally elongated with a lateral flange at one end and an integral,dome-shaped portion at the opposite end, the dome-shaped portion of eachsection being connected to the dome-shaped portion of the adjacentsection only at its lower end and at relative angles to each other ofless than 90 so that when said sections are hingedly closed incdge-to-edge contact to form the casing, the upper edge of the casing isscalloped longitudinally and defines a .4 top opening having aconfiguration which is substantially that of an equilateral triangle,said lateral flanges also defining a bottom opening of a configurationsimilar to that of said top opening, and said inner and outer sectionsbeing each provided with indentations on the outer surface andprojections corresponding to said indentations thereof, saidindentations each defining a projection on the corresponding oppositesurface, and the thickness of the projections being greater than thethickness of the sections between these projections.
